Use the data given to find the correlation coefficient of Height (explanatory variable – x) and PulseRate (response variable – y). Is that correlation coefficient significant? Explain why or why not. Find the equation of the regression line for those two variables with Height as the explanatory variable (x) and PulseRate as the response variable (y). Use the regression equation to predict what pulse rate somebody would have if they are 6’3” tall. Do you think your estimate in #11 will be reliable? Explain why or why not. If not, what is a better prediction?
